OPTIONS

19       This program follow the  usual  GNU  command  line  syntax,  with  long
20       options  starting  with  two  dashes  (`-').   A  summary of options is
21       included below.
22
23       -n N, --number=N
24              Stop the refinement process if the number of vertices is  larger
25              than N.
26
27       -c C, --cost=C
28              Stop the refinement process if the cost of insertion of a vertex
29              is smaller than C.
30
31       -f, --flat
32              Input is a flat file with three x,y,z columns  (default  is  PGM
33              file).
34
35       -r Z, --relative=Z
36              Use relative height cost for all heights larger than Z.
37
38       -k, --keep
39              Keep enclosing triangle.
40
41       -C, --closed
42              Close the surface.
43
44       -l, --log
45              Log evolution of cost.
46
47       -v, --verbose
48              Display surface statistics.
49
50       -h, --help
51              Display the help and exit.
